Description

Air supply

The present invention relates to an air supply device, and more particularly, to an air supply device capable of concealing a wire for supplying power to an electronic device in a rotatable state.

In general, firefighters who extinguish a fire are supplied with air through an air supply at a fire site. The air supply device supplies the air of the air box loaded in the form of a backpack on the back of the firefighter as a mask worn on the face of the firefighter. Therefore, the firefighter can smoothly extinguish the fire at the fire site.

In recent years, electronic devices such as microphones are built into the mask to fight fires more smoothly. These electronic devices are operated by wires which supply power from the outside of the mask.

Here, the above-mentioned electric wire is wired in parallel with the air hose which guides the air of the air box to the mask, and is fixed to the air hose by a member such as tape or cloth. In other words, the wire is fixed in a state overlapping the air hose. Then, the wire is mounted to the mask is wired to the mask through the inside of the pressure regulator to supply the mask by adjusting the pressure of the air supplied to the mask through the air hose to the pressure that can be breathed. At this time, the pressure regulator is installed in the mask is supplied to the air of the air box into the mask, or coupled to the exhaust port for exhausting the air inside the mask to the outside. Then, the wire is introduced into the pressure regulator and then connected to the wire extending from the electronic device inside the mask to the pressure regulator through a connector provided at the end. Thus, the wires supply power to the electronics inside the mask.

On the other hand, the air hose described above is rotatably connected to the pressure regulator in a ventilable state through the rotating member. Thus, the air hose can be flexibly coped with the flow while rotating the mask. That is, the air hose continuously supplies air to the mask even while it is being rotated. Of course, the worker can thereby proceed to work more smoothly.

However, such a general air supply device has a problem that can not provide a beautiful aesthetic because the wire connected to the pressure regulator is exposed to the outside. Of course, in order to solve this problem, even in advanced countries in Korea and foreign countries, various efforts have been made, but as described above, since the wires fixed to the air hose are rotated together with the air hose, to date, due to technical difficulties to solve the disconnection caused by the rotation, This situation is not solved.

In addition, since the wires are separated from the air hose separately, there is a problem in that a more beautiful aesthetic can not be provided due to the feeling of being scattered too much. In other words, the wires and the air hose do not form an integral form, such as "11" can not give a neat and tidy feeling. In addition, since the wire and the air hose interfere with each other, not only inconvenience in use, but also the wire is exposed to the working environment as it is, there is also a problem that the wire is broken or durability is reduced.

Of course, the wires and air hoses that are wired in parallel can be covered with a protective material such as heat-resistant coating or protective rubber tube to conceal the wires. However, in this case there is a problem that the weight of the wire and the air hose by the protective material. Therefore, the operator does not rotate the air hose smoothly by the protective material, the weight of the mask is weighted by the weight of the protective material, not only does not cause fatigue in the neck during a long time work can not be performed smoothly.

In addition, since both of the above-mentioned connector must be fixed to the pressure regulator by bolting, respectively, there is a problem that the assembly work is very inconvenient.

4, as shown in the ring holder 53, the coupling protrusion 53a on one side is fitted into the coupling hole 31h of the pressure regulator 30, and the other side is connected to the pressure regulator by the fastening screw 531. Since it is fixed to 30, it is easily assembled to the pressure regulator (30). In addition, since the air hose 20 is pivoted about the hollow shaft 35 by the rotating ring 36a which is inserted into the hollow shaft 35 and rotates, the air hose 20 can flexibly cope with the flow of the mask 10 described above. That is, the air hose 20 is rotated during the flow of the mask 10 does not interfere with the work activity of the wearer.

Referring to FIG. 6, the hollow shaft 35 has one side inserted into the pressure regulator 30 as shown, and then the fitting protrusion 38a of the protruding ring 38 is the fitting groove 53c of the ring holder 53. As it is coupled to the pressure regulator 30 is detachably fixed. Hollow shaft 35 is more firmly fixed as one side inserted into the pressure regulator 30 is caught by the clip (37). The hollow shaft 35 is rotated with the knob 34 when the knob 34 is rotated to rotate the flow control valve 331 built in the pressure regulator 30 to adjust the flow rate.

The rotary ring 36b is a hollow shaft 35 through a communication hole H on the inner circumferential surface of the air hose 20 introduced through the nipple 36a and a vent 352 of the hollow shaft 35. Guide to the inside of the pressure regulator 30 is supplied into the interior.

The wire 54 is guided to the inside of the rotary ring 36b through the wire guider GD formed in the rotary ring 36b, and then wound around the winding sheet 35d of the hollow shaft 35. At this time, the wound wire 54 is concealed by the shielding wings (CW) extending to the rotary ring (36b). Thus, the wire 54 is supplied to the pressure regulator 30 in a concealed state. In particular, the wire 54 is supplied to the pressure regulator 30 in a more completely concealed state when inserted into the air hose 20 as shown.

Here, the air hose 20 and the wire 54 is reduced in weight by insert processing. That is, the total weight of the air hose 20 and the electric wire 54 is reduced. This is because the covering of the electric wire 54 can be omitted. Therefore, in this case, since the protective material as in the related art can be omitted, the overall weight can be further reduced, thereby reducing the operator's neck fatigue caused by the heavy weight during long working hours and providing smooth working conditions. have.

Meanwhile, when the clamp connector 52 of the clamp 13 is coupled, the ring holder 53 supplies the power of the wire 54 to the clamp 13 through the terminal T. Therefore, the clamp 13 smoothly supplies power to the electronic device as described above.

Referring to FIG. 7, the rotation ring 36b rotates together with the rotation protrusion 36c formed at one side. At this time, the rotary projection (36c) is rotated along the other side stopper (32b) of the boss shape formed in the pressure regulator (30). When the rotary projection 36c is rotated to the upper portion of the other stopper 32b, the rotation is suppressed while being in close contact with the outer circumferential surface of the other stopper 32b which is formed to gradually open upward. That is, the rotation protrusion 36c cannot be excessively rotated upward by the interference of the other stopper 32b.

Referring to FIG. 8, when the rotation protrusion 36c is rotated downward, the rotation protrusion 36c is caught by one stopper 32a protruding from the pressure regulator 30, thereby suppressing rotation. That is, the rotation protrusion 36c cannot be excessively rotated by the one stopper 32a. Accordingly, the rotational angle 36c is controlled by the one stopper 32a and the other stopper 32b described above. Of course, the rotation angle of the air hose 20 is also controlled accordingly.

As such, the reason for controlling the rotation angle of the air hose 20 is to prevent disconnection of the wire 54 wound inside the rotation ring 36b as shown. This wire 54 is wound about 1.5 times inside the rotary ring 36b as shown to prevent disconnection as much as possible. Therefore, since the length of the wire 54 is extended by the number of turns, the wire 54 is not tensioned when the air hose 20 is rotated.

The present invention is not limited to the above-described embodiments, and of course, modifications may be made by those skilled in the art without departing from the spirit of the present invention. Therefore, the scope of the claims in the present invention will not be defined within the scope of the detailed description, but will be defined by the following claims and their technical spirit.

The present invention can prevent the disconnection of the wire even when the wire is integrally formed in the rotating air hose, it is possible to simply configure the configuration of the air supply device, it is possible to transfer the power or voice signal to the inside of the mask through the wire Therefore, the air supply apparatus can be upgraded and the convenience can be improved.
